Hello,

We are using two AC450 controllers for our 2 Nos. 18MW Powerplant. And AdvaCommand 1.7 as MMI. Both the units are controlled by seperate dedicated controllers sitting on the same MB300 network. We are facing problem that whenever fault is generated in unit one object it is also affecting the unit II object. I mean to say if some fault (say Local stop) is coming in unit 1st MMCX38, it is also tripping the drive of unit II which is having the address MMCX38 in the other controller. Be informed that there is no any physical connection between these two objects. We have already done the object reference maintainence (Retranslation) but the problem is still persisting.

Any firm solution will be highly appreciated.

Regards,

Dosani M.

 

If you use 2 ACs on the same bus, connected to 1 or 2 operator stations, it is better to use different names for every I/O, because the operator station links by name.
If an event happens on one station, it is probably the operator station that causes the other station to trigger.
If you use 2 operator stations, you can use the option "process sectioning" to instruct which station should respond to wich AC.

If the operator station is common for both, you have to use different names for all DB-elements.

 

If you are running Advacommand 1.7, you are on old UNIX machines. This also sounds like an APC application. If you are interested to upgrade your workstations as well as APC, then visit us at http://www.workstationsexpress.com and email us to discuss your needs.
